does the pink wire at the ICM and the crank sensor show 12 volts with the key ON ?
if both show 12 volts with the key ON then can you connect a test light with the test light clip connected to battery 12 volts and unplug the ignition coil electrical connector and touch the test light to the white/black wire terminal in the connector and crank it over will the test light bulb blink ?
are you able to do those tests ?
